UpdateLayout with ObservableCollection change

Sehe

I recently updated my application to the 2011 Q3 DLLs. I have a tab control that binds to an ObservableCollection for the ItemsSource. I have to add an item to the ObservableCollection in code. I used to be able to do an UpdateLayout on the tab control, and it would add the new tab. It doesn't do this anymore. I can set the ItemsSource to null and back to the ObservableCollection to get the tab to show up, but that has other very bad consequences in my application.

Have you seen this problem with the UpdateLayout not working? Do you know of a work around?
